Who can simply explain quantum theory?

Quantum theory means that a physical quantity is quantized if it has the smallest indivisible basic unit, and the smallest unit is called quantum.

In Newtonian mechanics (or classical mechanics) system, energy absorption and release are continuous, and matter can absorb energy of any size.

Later, it was found that only a certain order of magnitude (hv) was taken as the minimum unit to truly absorb and release energy, where H was the most commonly used Planck constant in quantum mechanics and V was the electromagnetic frequency.

Due to the small magnitude of Planck's constant (-34th power of 10), Newtonian mechanics agrees well with the experiment on a large scale, but it deviates greatly on a small scale.

Therefore, Schrodinger established the Schrodinger equation based on Planck's quantum theory system, which opened the beginning of quantum mechanics.

Schrodinger's Quantum Theory

Schrodinger, a famous Austrian physicist, put forward a famous quantum mechanics thinking experiment, which aims to clarify the principle of quantum superposition on the micro scale from a macro perspective and help people understand images.

In an ideal experiment, suppose a cat is in the same box with a bottle containing radioactive substances. There is a 50% chance that the radioactive substances will decay and produce poisonous gas. At this time, the cat will be poisoned by poisonous gas, and there is a 50% chance that the radioactive substances will not decay and the cat will not die.

Regardless of any other factors that interfere with this system, the survival of cats is only related to whether radioactive materials decay or not.

And anyone outside the box doesn't know the cat's life and death until he opens the box and observes it. Cats have a 50% chance to live and a 50% chance to die.

At the same time, in the same place, this superposition of life and death exists for people outside the box.
